CD ROM SPECIFICATIONS

Definition
CD-ROM means Compact Disc-Read Only Memory.

Track
CD-ROMS are organized in a single track that spirals from the center of the disk to its outside.

The Pits
The data is recorded as a series of pits burned into the underside surface of the platter.

The Laser
A laser beam is used to detect whether specific points on a disk are pitted or not and that information is translated into data that your computer can read.

Speed
CD-ROM drives are grouped by transfer speed, with a 150Kb/second called a single speed, 300 Kb/second called a double speed(2X), up to today's standard of 40X.
